WINDOW CONSTRUCTION.

Application filed July 24:,

To all whom it may concern Be it known that I, GEORGE S. BENJAMIN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of li lichigan, have invented a new and useful Vindow Construction, of which the following is a specification.

This invention relates to window constructions and more particularly to window constructions wherein a sliding sash member is also hinged so that it may be swung inwardly to facilitate cleaning.

It is an object of the invention to provide a window of the described character having two sliding sashes which are adapted to both be swung inwardly on suitable hinges without interfering one with the other; and it is a further object to provide for effecting such an adjustment of the sashes while both are either raised or lowered, or while one is raised and the other lowered.

The invention further consists in various structural features which facilitate manufacture, secure a high degree of strength, and are conducive to ease of operation, ready installation and an attractive appearance.

A preferred embodiment of the invention is illustrated in the accompanying drawings, wherein,

Figure 1 is a view in interior elevation of the improved construction, both sashes being shown in their normal closed positions.

Fig. 2 is a cross-sectional view of the same taken on line 22 of Fig. 1, the central portions of the sashes being broken away.

Fig. 3 is a vertical sectional view taken upon line 33 of Fig. 1.

Fig. 1 is a cross-sectional view cutting the upper sash and showing the lower one in plan, both sashes being shown swung inwardly at right angles to their normal positions.

In these views the reference characters 1 and 2 respectively designate the upper and lower sashes of the window, and 3 and 4 indicate the side j ambs of the window frame. The jamb 3 carries within the window opening two adjacent channel-shaped members 5, preferably formed of sheet metal, and ex tending substantially the full height of the window opening. Any suitable means may be employed to secure said members to the j amb carrying the same, screws 6 being employed for that purpose in the drawings. The channel members 5 are slidably engaged by complementary channel members 7, which Specification of Letters Patent.

respectively form hinge mountings for the two sashes. The engagement between the complementary channel members 1s estab lished by flangmg the adj oining edges of the I same inward and returnbendi11g the flanged edges of one of the members to embrace the flanges of the other. Thus, in the drawings, the members 5 have their edges flanged oppositely inward, as indicated at 8, and the edges of the members 7 are bent to form opposed return-bent flanges 9 loosely embracing the flanges 8. Each sash is mounted upon the corresoonding channel member 7 by two vertically spaced. hinges 10. both leaves of said hinges being intermediately bent a right angle. As is clearly shown in Figs. 2 and 1, however, the hinges of the respective sashes are oppositely bent, so that the hinge pintles 11 of the upper sash are offset away from the jamb 3, while the pintles 12 of the lower sash are offset toward said jamb, and lie close adjacent thereto. The advantage of thus bending the hinge leaves so as to oppositely offset the pivotal axes of the two sashes is made readily apparent by Fig. 1, wherein it is seen that both sashes may at the same time occupy positions transverse to the frame of the window without interfering one with the other.

A stop strip 13 is secured to the jamb 4; within the window opening and extending the full height of said opening to formaslide guide for the upper sash 1, and to restrain said sash from any outward yielding. The two sashes overlap each other sufliciently, even when in their respective upper and lower limiting positions, to prevent inward swinging of the sash member 1 until the sash 2 has been unlatched. The latch means for the sash 2 consists of a. bolt 14, which is best shown in Fig. 2, which bolt is socketed in the side piece of said sash adjacent the j amb 4 and is acted upon within its socket by a coiled spring 15 maintaining it normally on gaged at one end with a vertical groove or channel 16 in said j amb. The other end of said bolt projects, as is seen in Fig. 1, sufficiently to be readily grasped to permit dis engagement of the bolt from the channel 16 when it is desired to swing the sash 2 inward on its hinges. Obviously the described latch arrangement is one which offers no interference to the normal sliding adjustment of the sash 2.

Each sash is counterbalanced by a weight 17 suspended from a cord 18, which, passes over a pulley 19 journaled in the upper end of the jamb 3 and is attached to channel member ,7 of said sash by an eye bolt 20.

The described construction possesses numerous advantages, primary of ivhich is the adaptability of the two sashes to occupy-at the same time their inwardly swung positions shown in Fig. 4. This not only greatly facilitates Washing of the window, but allows a very thorough ventilation to be effected, when desired. In some cases, also,

the described adjustment may be utilized to permit large articles to'be readily passed into or out of a building through a window.

opening. Also the use of sheet metal members to slidably mount the channels permits of a very strong yet compact constructlon and is favorable to quantity manufacture at low cost. 1

I claim In a Window construction, the combination With a frame having a Window opening, of a channel member vertically extended upon said frame within said opening and having. its edges flanged toward each other,

a complementary channel member having its edges flanged toward eachother and returnbent to slidably embrace said flanges of the first mentioned channel member g and a sash hinged to said'sliding chai'lnel'member.

In testimony whereof I sign this specifica-
